hey, ive been outta this stuff for a few years but as usual got the itch and bout a .21 t-maxx. I ripped it apart and rebuilt it but ran it before that and it ran fine. i finished it last night, started it up today and it the damn thing is driving backwards. when ya spin the spur gear it also only engages when spun in reverse. is my engine spinning the wrong way or something cause i am pretty much baffled by this one...any help will be appreciated, thanx guys
